William Tilghman (1756 - 1827)

Relationship to the Speculation Lands: 
A relative of the Coxe family, Tilghman was charged with monitoring and maintaining the mortgage for the Speculation Lands and the trust established for Tench Coxe by his father. 
William Tilghman was the Chief Justice of the Pennsylvania Supreme Court, and one of the "midnight judges" appointed by President Adams to the Third Circuit Court in 1801. He was the grandson of Tench Francis and the brother of Tench Tilghman, a Revolutionary War soldier who served as an aide-de-camp to General Washington at Valley Forge. Tench Tilghman also served as secretary and treasurer to the Continental Congress in 1775. William, his younger brother, was a jurist in the county of Talbot in Maryland. He moved to Philadelphia where he began to practice law in 1793. In 1801 he became Chief Justice of the Pennsylvania Supreme Court.. Like his friend, Stephen DuPonceau, Tilghman was also active in the American Philosophical Society and served as its President from 1824 until his death in 1827. In 1809 he was directed by the Pennsylvania state legislature to prepare a report on the English statutes in force in Pennsylvania. A balanced judge, an advocate of children's rights, keenly interested in agriculture and home industry, and unpretentious in nature, he was by all accounts, an excellent choice to oversee the tumultuous financial affairs of Tench Coxe.
